Is it posible to use the psp as an USB wireless internet adapter?
or has someone else made this already? |

| It would be theoretically possible, however it wouldn't be practical :) |

| No one has made any largely successful attempt to program the USB as a custom device. |

Yes, but there you had libusb which was already worked on by many people to port from previous hardwork on various other platforms.
I doubt anyone has implemented any kind of device like a keyboard or mouse, or a network adapter no less. I assume such things are usually implemented with one chip solution hardware and not by manually programming the USB interface on said device. |

Then you would be wrong, there is nothing particularily special about a network interface which means it has to be implemented in a specific device chip.
Just because I used libusb doesn't mean it wasn't a custom device, what you _actually_ mean is no-one has written a class device which implements either an existing device protocol or a standardized protocol.
I could almost certainly write you a network device which uses a simple protocol and write you an NDIS driver to add an ethernet device (but I won't) and you _could_ write a standard network class device but there are some things missing from people's understanding of the Sony USB controller which makes it slightly less than simple. But in the end the hardest issue would be working out how to talk to the wifi card at a low enough level rather than at the IP level.
In the end the fact that noone has bothered to write another USB device is more indicative of people's laziness and lack of ability than anything else :) |

Thats exactly what I meant. I have experience programming PIC microcontrollers as custom USB devices. (Its usually easier to make it appear as some kind of HID device that windows already has drivers for and read it accordingly in your PC side app, instead of requiring a separate driver like libusb). |
